+Passing the tests is very easy. There are just five functions to implement:
 
-- `zones()` - list domain zones (i.e. example.co.uk, example.com)
-- `set()` - set a TXT record in a zone (i.e. `_acme-challenge.foo` in `example.com`)
-- `get()` - confirm that the record was set
-- `remove()` - clean up after the ACME challenge passes
+- `init(deps)` - (optional) this gives you the `request` object you should use for HTTP APIs
+- `zones(opts)` - list domain zones (i.e. example.co.uk, example.com)
+- `set(opts)` - set a TXT record in a zone (i.e. `_acme-challenge.foo` in `example.co.jp`)
+- `get(opts)` - confirm that the record was set
+- `remove(opts)` - clean up after the ACME challenge completes
 
 The tests account for single-domain certificates (`example.com`) as well as multiple domain certs (SAN / AltName),
 wildcards (`*.example.com`), and valid private / localhost certificates. No worries on your end, just pass the tests. 👌

 ## Reference Implementations
 
-These are plugins that use the v2.7+ (v3) API, and pass this test harness,
-which you should use as a model for any plugins that you create.
+- Compatibility
+  - [x] Let's Encrypt v2.1 / ACME draft 18
+  - [x] Node v6+
+  - [x] Chrome, Firefox, Safari, Edge, etc
+- Quality
+  - [x] Written in VanillaJS
+  - [x] No compliers or build scripts
+  - [x] Simple, minimal code, in a single file
+  - [x] **Zero dependencies**
+
+These libraries are useful as a model for any plugins that you create.
